Hi Every Body, i have plan to porting my existing projects from MSSQL Server 2000 to PostgreSQL, but i'v got several problems with pgoledb when i use it with Ado component in delphi. 1. is schema displaying not supported on pgoledb, because when i used zeos (open source dbc component) they can displayed on it with format [schema].[table_name] not just [table_name]. 2. varchar and char become [MEMO] in DBGrid,whats wrong with this? 3. i'v one column in my table that using int4[] data type, but when i open it in delphi i'v got an error message "Query returned unhandled type 1007", what's should i'v to do? 4. thanks for all. My Specs : - Win 2000 Advanced Server Powered NAS - Borland Delphi 7 - PGOleDB 1.0.0.19 - PostgreSQL 8.1.1 - Intel P4 2.4 GHz, 256 MB RAM.
